I did this same thing nearly 2 years ago. Except instead of using a spare model train controller (I have one of those, actually), I used a power supply I had lying around from another project from Radio Shack that has a switchable voltage with about 5 presets. Got my rare earth magnets from RS as well.

It's "ghetto", but completely functional.

It can make a funnel in 2l of water though.
The trick to getting two magnets to work, is first getting the polarity of the two magnets right, the second is getting the center line of the two magnets to line up correctly with the center line of the fan..... otherwise, the stir bar will "orbit" around the center of rotation and ultimately be tossed.

so:

1. magnets must be equidistant from the center of the fan
2. magnets must have the proper polarity alignment

stir bar (- +)
mag 1 (+) (-) mag 2

3. center line of magnets must align with center line of fan.

I also found it helpful to space the magnets so the end of the stir bar was even with the center of each magnet

hope that helps

I tried this but apparently my fan is not powerful enough, it couldn't move the magnet, using an old school Lionel transformer and a 100mm fan, a magnet from a hard drive.

Any tips/brands to use? I already wrecked one fan.
